Commercial Masterkey Systems

Master key systems
Not to be confused with keyed alike systems, where all locks are keyed under the one key. “Master key system” is a term used to describe how we manage and control keys, and limit access through individual doors. Prior to electronic access control systems or mechanical digital locks this was the only way to restrict access to certain areas without the expense of an access control system. Master key systems are still used predominately in small to medium sized businesses. Typically a worker may need access through the front gate and to their office door and as such a key can be given to them which only allows that access. However the master key will allow the manager access to every lock in the building.

Restricted master keys systems
As the name implies these systems restrict the availability and distribution of key blanks and barrels. There are many providers of restricted key products through locksmithing channels and basically they all have a registered or restricted design pattern on the key or the barrel. The restricted system provider supplies to the locksmith the system under an agreement that is both legally and ethically binding which ensures the integrity of the restricted product. The biggest advantage of this system is the locksmith controls the system. Whenever the client needs additional keys they must order the keys with a signed request. The client nominates a responsible person within their organization to be the designated signatory and a sample of that persons signature is kept on file to verify each order. In addition all restricted keys are individually stamped with system number, rank and sequential generation, which can be used to track keys and design of the system.
This has been the industry standard worldwide for many years and is a very cost effective way to ensure security over locks and keys.

High security restricted master key systems
Unfortunately the freedom of expression that has come with the Worldwide Webb there is also a downside and the security industry has not been excluded, there is now an abundance of websites only to willing to share for fame or fee ways to breach many security systems. The first to suffer has been the humble “in line pin cylinder” which is the basis of approximately 98% of all locks in Australia. The solution is to install one of the High Security locking systems now available such as EVVA which can withstand many types of attack. EVVA uses sidebars and multiple profile barrels, call us to discuss any aspect of the above.
